"Dig Deep" is an original song introduced in the eleventh episode of the first season of the musical TV series Smash, entitled " The Movie Star". It was written by Marc Shaiman and Scott Wittman, but within the show's universe, it was written by the songwriting team of Tom Levitt ( Christian Borle) and Julia Houston ( Debra Messing) for the Bombshell musical they are working on about Marilyn Monroe.
In "The Movie Star", movie star Rebecca Duvall ( Uma Thurman), who is now playing Marilyn, and the Bombshell ensemble are in a rehearsal room acting out an Actors Studio session learning some acting tips from the teacher, and then breaking into the song, while the show cuts away to a fantasy sequence of Rebecca and the ensemble dressed in 1950's clothes and performing the song.
Ivy Lynn ( Megan Hilty) reprises the song in the eleventh episode of Season 2, entitled " The Dress Rehearsal", as part of Broadway previews for Bombshell.
The song was initially released as a single with Thurman's vocals but is no longer available in that version. The version with Hilty's vocals is currently available on the cast album Bombshell.
